OSBYTE &16 (22) - Increment Polling Semaphore

   This call increments a counter, which if non-zero will cause a 100Hz
   service call (type &15) to be sent the paged ROMs. This allows a way
   for ROMs to poll hardware which doesn't offer interrupts.
   
   Implemented on Electron and MOS 3 onwards
